http://perforce.freebsd.org/chv.cgi?CH=131627 Change 131627 by hselasky@hselasky_laptop001 on 2007/12/25 22:44:31 Need a function to clear interrupts. Probably this is not the right way to do it. We need an interrupt-sharing framework around this, but until further it is good enough, hence there is only one device using these kinds of interrupts.
